Here's how I parse things:
The Empulse cost about 30% more than I paid for my 1999 BMW, when it was new in 1999. Performance numbers are about the same, range is the same. The BMW I can extend the range (refueling) in about 10 minutes, and is also known to be insanely reliable. Maintenance is more, but repairs (from what I've seen some Empulse owners go through on the forum) is arguably less.
So, 30% premium for less maintenance and almost no performance gain? No thank you, Brammo.
Enertia+? Costs about 30% more than my 2006 DRZ400SM did when new. Same as above, range is about the same, same fueling restrictions (moreso, since it charges off 110), performance is about the same (the DRZ, if you push it over 60 and hold it there for long periods, like a highway commute, you're pretty much cooking your engine).
But, for commuting? Wow! Heavy traffic, no need to slip a clutch? It's great for commuting, with 2 limitations: Off the line it's a pig, so splitting lanes is unsafe, and the saddle bags: They're too small to hold a laptop, and ... Givi costs as much as BMW luggage, but feels like a cheap milk carton. I've seen BMWs laid down on plastic luggage, and the lids get scraped but no cracks or collapses. So, I feel some of the things that would make it a nicer commuter (ability to get out of its own way, or tackle steep hills even, and the ability to carry *anything* physically large that's not on your back) was hurting it.
I was really hoping that Polaris would've worked more in that direction. Most people aren't aware they've had e-bikes (like, the kind with pedals!) for some time, continuing the Enertia+ would've been a great gap filler between someone that may need to carry their bike in to their apartment and someone not ready for a full-fledged moto with a transmission.
